Compare and contrast granite and rhyolite.

Answer:

Granite and rhyolite are both felsic igneous rocks with similar mineral compositions, including abundant quartz and feldspar. Granite forms underground from slowly cooling magma, giving it a coarse-grained texture with large visible crystals. Rhyolite forms at or near the surface from rapidly cooling lava, giving it a fine-grained texture, although it can sometimes be glassy or porphyritic.
